Would you mind if I played around with it in photoshop? All proper credit will be given where it is due. If you see this as something you're not comfortable with, it will not hurt my feelings if you say no. I do understand.

It depends on what you do with it. My model release allows me to use her photo, and to manipulate it as I wish, provided the result is not humiliating or demeaning to her. If you do something with it that she is upset about, I am responsible and liable. So, here's what I would suggest.

I will email you the raw file (NEF), you play with it, and send me the result for my review. If it is not likely to upset the model I will authorize you to display it. Does that seem fair to you as well as to the model?
